PEUTECIJIVE E THITEEZ-L'E- FOR BUBBINS.

Application filed August 15, 1322.

To all whom it may concern:

Be it known that We, WILHELM Ramses, manufacturer, a subject of the German Re public, and residing at lvIuniclrGladbach, Germany, ltheydterstrasse i8, and GUSTAV liaittison, engineer a subject ofthe German Republic and residing at Munich- (Zrladbach, Germany, Weststrasse at, have invented certain new and useful Improvements in Protective Thimbles for Bobbins of Which the followingis a specification.

)ur invention relates to improvements in protective coverings for bobbins, particularly those of the so-called bottle bobbin type.

During transportation or storage the yarn body of bobbins is liable to damage by reason of many causes. Friction with othei bodies results in weakening of the strands and consequent breaks on the machine While exposure results in an accumulation of dust and dirt and frequently in a fading of the color. For these reasons it is essential that each bobbin be protected by a thiinble or laet which shall be at once strong,- durable and easy of application and removal.

Such a device is illustrated in the accompanying drawing in which 0. represents the yarn body, Z) the head of the bobbin. 0 its base and Z the protective jacket.

In carrying out our invention We form a light hull of metal or other suitable material which substantially conforms to the shape of the yarn body, yet is large enough so that its inner surface Will not come into contact therewith at any point when in position.

Serial No. 582,074.

lit its base the jacket is provided With suitable means c on its inner circumference for engaging in a circumferential groove (Z pro vided on the base 0 of the bobbin. The iower edge of the j acket may be spun back I to give additional strength.

i fhen the j achet is placed in position, the bobbin head 0 comes into contact With the couver" nt Wail of the jacket at and is therco-x centered. iVhen in this position the re iining means has come into gripping contact with the groove d and the bobbin is thereby maintained in its centered position. Since the base of the bobbin is of slightly larger,- circumference than the yarn body, the latter is held free of contact with the acket Wall and consequently protected from any possible damage.

Vi e claim:

l-i protective covering for bottle-shaped bobbins consisting of a metallic thimble of slightly larger diameter than the yarn body and conforming substantially in shape therewith so that when in position the bobbin hard is centered and supported by the convergent end of the thinible and its base by the thimble Wall, whereby the yarn body is Withheld from contact With the thinible.
